This paper studies the precision, and the
accuracy, of an underwater target tracking system,
using range-only and single-beacon methods, in
shallow waters environments. For this study, different
field tests have been ...

Nowadays, the use of autonomous vehicles for
ocean research has increased, since these vehicles have a better
cost/performance ratio than crewed vessels or oceanographic
ships. For example, autonomous surface vehicles ...

[ANGLÈS] In recent decades there has been progress in the study of oceans, especially to exploit natural resources (fisheries and oil fields) and to study climate change and the impact of this on the various marine species ...

This
work presents a description of Guanay II AUV ballast system, which
consists in 3 blocks of foam distributed along the vehicle, and a weighs
system in the central part in order to realize a fine tuning. Likewise it ...

The AUV Guanay II is a vehicle developed by
SARTI research group of Universitat Politècnica de Catalunya with the objective of providing a platform for measuring
oceanographic variables, such as the temperature and ...

This paper presents the design and construction of Guanay II vehicle. It is an autonomous underwater vehicle that navigates over the sea surface and, at certain fixed points, dives vertically to obtain a profile of a water ...

The autonomous underwater vehicle(AUV) Guanay II
was designed to navigate on the surface of the sea, and to realize a
vertical immersion in specific points. This vehicle has three thrusters
located on stern, oriented ...

The autonomous underwater vehicles (AUV) carry out
inspection missions and intervention on known and unknown
environments, where it is important to ensure their safety. The
ability for obstacle detection and their ...

Autonomous underwater vehicles (AUV)
perform inspection missions and intervention in known
and unknown environments, where it is necessary to
ensure their safety. The AUV must have the ability to
detect and avoid ...

This work proposes the development of a control
system for an autonomous underwater vehicle dedicated to the
observation of the oceans. The vehicle, a hybrid between
Autonomous Underwater Vehicles (AUVs) and Autonomous
Surface ...

Most Autonomous Underwater Vehicles (AUVs) mount an Acoustic Doppler Current Profilers (ADCP). Data from this sensor are rarely used in scientific studies due to the complexity of its processing and the lack of validation. ...

Corrosion due to seawater studies are urgently required for a safe technology
development. Some studies demonstrated that the corrosion rates for most
alloys could be four times less than surface corrosion rates. A device ...
